Refractive Errors

Refractive Errors

Myopia, hyperopia, and astigmatism can be treated with glasses/contacts, Lasik, or PRK. Presbyopia is currently only treated with glasses, multifocal contact lenses, multifocal IOLs, and monovision where one eye is corrected for distance and the other for close vision. Ladarvision is an advanced Excimer laser system manufactured by Alcon and is approved to treat myopia, hyperopia, and astigmatism.

Myopia

Myopia is a condition of the eye that results in blurred distance vision. The cornea and lens focus light rays from distant objects in front of the retina. This incorrect focusing of light results in blurred images of objects at a distance.

Hyperopia

Hyperopia is a condition of the eye that most commonly results in blurred close vision, although moderate to severe hyperopia may also result in blurred distance vision. The cornea and lens focus light rays from objects behind, rather than directly on, the retina.

Astigmatism

Astigmatism, another cause of poor vision, occurs when the eye is football shaped. Here, images focus on more than one point in front of, or behind the retina. The result is that all images, whether near or far, may be blurry. In mixed astigmatism, symptoms of myopia or hyperopia are combined, resulting in the overall inability to see images clearly.

Presbyopia

Presbyopia is a condition occurring most commonly in people over the age of 40, where the eye can no longer accommodate for near or reading vision. The crystalline lens of the eye loses its elasticity. The individual is no longer able to read clearly and requires reading glasses.
